Pentagon Loses War to Zap Airborne Laser From Budget
The Airborne Laser would seem to be a viable target. It isn't nearly
powerful enough to hit far-away launch sites. The aircraft is essentially
a flying chemical plant, its interior filled with vats of toxic materials
used to power the laser.
Mr. Gates said in 2009 that a fully operational Airborne Laser fleet would
require 10 to 20 heavily modified 747s, each costing a billion and a half
dollars to build.

2. 中国人共餐,几乎每天和家人交换唾液。

airborne这个词容易让人误会,其实大部分细菌和病毒都不能单纯的“airborne”,都
是要附在微尘或者微型液滴上。
要把culture flask 里的培养液搞成airborne droplet,除非你拿着瓶子狠狠地甩来甩
去弄出一堆泡沫,然后把瓶口打开大口大口的对着瓶子呼吸。
这种事情除非发神经或者要自尽,否则没有人会做吧。

以为美国医疗硬件这么先进,所以预防传染病就很先进,事实上不是这样的。
因为美国的传染病总得来说很少,加上人口密度低,主要流行的就是流感,所以医院/
医护人员的防感染意识和设施都不行的。目前看,如果美国大城市比如CHICAGO爆发
SARS,可能比中国都严重。
首先是门诊的TRIAGE/接诊,根本没有人带口罩。即使是流感季节。这样如果比较严重
的AIRBAORNE病人来了,直接就传染个护士和接待人员。
住院部科室里更没有人带口罩了。诊所也是一样。
其次是,除了极少数科室,比如OR/OB,大部分护士的工作服是自己买的,自己穿回家
,自己回家洗。如果护士已经中招了,那她在来回的路上,在家里,肮脏的工作服早就
传给别人了。反正我下班经常顺路买东西或吃饭。就不要说那些坐公共交通工具上下班
的人了。
第三,很重要的一点是因为美国传染病人少,所以没有专门的传染病医院,绝大多数医
院没有传染科。大部分需要隔离的病人,就是临时把门关上,门上放个标志。AIRBORNE

菌班著名男护士THR,长期浸淫在吃人不眨眼的霉国医院的体制内,深受霉国医院的
体制的洗脑,并且拿着病人和纳税人的钱当着间接五毛。(当然这么说也不公平,
真实情况是,医院领导和疣太们拿大头,THR最多是喝汤而已。何况THR好歹也付出劳动
不过护士这行性价比不错,不然THR怎么有底气经常在版上号召大家转学护士专业呢。)
所以每当版上有遭受霉国黑心医院保险公司勾结乱收费的天价账单,
以及被庸医误诊malpractice又打死不承认的病人诉苦时
THR大部分时间总是站在霉国医疗这一边,而与广大劳动大众站在对立面
结果,ebola一来,暴露了霉国医院的本质:霉国医院,并不是与医护人员同一阵营
相反,霉国医院只是为了疣太阿三统治阶级服务,他们才不管你们这些小护士
的死活呢。霉国的医院,在病毒黑五类面前,哪怕连任何最基本的防护都没有
如此一来,受害的只能是奋战在一线的护士,以及二线的医生。
霉国医院不拿人当人,收了病人的钱,还要把护士的命给搭进去

I-131是作为carcinogenesis研究用的,研究的是low dose long term biological

你对空气传播(Airborne transmission)引用的恰好就是我前面说的呀,The

而飞沫传播术语是droplet transmission, 这两者还是有区别的:
